SECTION 1: INTRODUCTION
1.01 This manual is to help the operator understand the operation of the
electronic panel of the machines.
These new testing machines are an easy-to-use range of compact machines
for determining Tension, Compression Shear, Flexure and other mechanical
and physical properties of materials. Due to variations in international
standards of units in force and extension, the tensile test machines have the
ability for the operator to select a one of two standards for Force Units
(Newtons and Pounds) and either Inches or Millimeters for the Extension
Units.
1.02 All the controls are located on the front panel, which has large, easy-toread backlit 2-line LCD display and a numeric keypad. The display unit
shows the force and displacement values. Crosshead control keys are
provided for moving crosshead up or down, or to start a test, or to get access
to various test parameters, for example, displacement or speed of crosshead.
The numeric keypad permits the inputting of test data.
1.03 There may be many aspects of material testing not covered in this
operation manual in particular the type of grips used and additional optional
equipment (for more information see our page in Internet:
1.04 All machines are provided for voltages 230 VAC or 115 VAC.
5
SECTION 2:GENERAL SPECIFCATIONS
These specifications apply to all models of the Tensile Test machines.
2.01 Force Measuring System - Full bridge strain gauge load cell of Z-Beam construction
for use in tension or compression. These interchangeable load cells are available
from the maximum capacity of the load frame, down to 5N.
2.02 Force Measuring Resolution - ±17 bit (=18 bit) of load cell capacity over the full
range (nominal).
2.03 Force Accuracy - ±0,5% of the indicated load from 2 to 100% of load cell capacity
and 1% down to 1% of the load cell capacity.
2.04:Force Sampling Rate - 50 Hz nominal (optional up to 800 Hz).
2.05 Extension Resolution - 0.001 mm (0.0001in.) of the full crosshead travel.
2.06 Operating Environment – All machines are designed to operate in temperatures of 0
to 38°C (32 to 100°F) with a non-condensing atmosphere of 10 to 90% Relative
Humidity.

SECTION 3: CHECKING CONTENTS
The machines are shipped completely assembled except for the optional accessories.
The basic machines are supplied with the following items, please insure that these are
included for the installation:
- Z-Beam Load Cell at or below the maximum capacity of the load frame;
- two Grip Pins (8 mm) for an adapter;
- operating instruction manual;
- load cell calibration certificate;
- one USB Serial Port Lead for external computer control;
- one 220 V cable.
The following diagrams are to help to identify each item:
Number Of Machine:
On the backside of each machine you find the number (Typ Nr.). Please use it for
future reference.

SECTION 4: POWER ON CHECKS
4.01 Power On/Off Switch The On (1) and Off (0) power switch is located on the back side
of the machine and should be in the Off (0) position before applying power to the machine.
The picture below indicates location of the power switch:
4.02 Emergency Stop Push Button The Emergency Stop push-button is located on the front
panel of the machine.
To activate the emergency stop you have to push the button. To deactivate the emergency
stop turn the button to the left and the button jumps out.
The picture below indicates location of the emergency stop push-button:
4.03 Mechanical Limit Switches Before attempting to move the crosshead in either direction
it will be required to set the mechanical crosshead limit switches. The purpose of the limit
switches is to reduce the travel of the crosshead enabling a safe working area. A typical
8
example is to protect the load cell and attachments for unforseen overtravel and in doing so
avoid a collision. These limit switches are located on the left hand side of the machine.
The diagram below shows the location of the mechanical crosshead limit switches:
The limit switches are held in position by a locking screw. To set the limit switch unlock by
turning the locking screw in an anti-clockwise direction and slide to the required new
position. To lock limit switch rotate locking screw in a clockwise direction. (Note: To
eliminate slippage re-tighten locking screw securely).
The diagrams below indicate mechanical crosshead limit switches:
Release Upper Limit Switch, move
crosshead to a new position, slide
limit switch to crosshead striker,
re-tighten.
Release Lower Limit Switch, move
crosshead to a new position, slide
limit switch to crosshead striker,
re-tighten.

The [Menu] Key
With this key the operator can make settings for the next test. The
adjusted settings should be confirmed with the [Return] key.
If you press the [Menu] key, you will see the following:
ENDPOS - means “Test Extension”.
The range is possible from 1 mm to 540 mm (for the smallest version of
the machine), except for the length of grips and specimen. Positive
values mean tensile test; negative values mean compression test. In
order to change from – to + you have to press the [Down] key.
V - means “Test Speed”.
The range is from 0,5 mm/Min to 500 mm/Min (only positive values
are possible).
F-LIMITS - means “Force Limit”.
The Force Limit can be used to protect tooling rated lower than the
load cell capacity, to end a test when that force is reached.
F-DELTA - means Force Delta.
Force Delta is the sensitivity for detecting the rupture of a specimen,
i.e. the value of 200N means, if during a tensile mode the load
decreases more than 200N/50ms, the rupture is detected and the test is
finished.
i value is too low rupture is not detected by the maschine and runs till
end of setted movement
F-MAN - means Jog Speed.
The range is possible from 1 mm/Min to 500 mm/Min.

SECTION 7: LOAD CELL
7.01 Fitting Load Cell:
The Z-Beam type load cell are mounted under the moving crosshead. Your machine
will be provided with a load cell equal to or less than the maximum capacity of the
machine. These interchangeable Load Cells are available in capacities from 3 kN
down to 5 N. Connect the load cell by plugging the 5 pin connector into the load cell
socket on the rear side of the machine.
7.02 Limits of the Load Cell:
Load Cell should not be deformed more than maximum 0,2 mm in both directions.
By doing pressure tests be sure that you do not bend a load cell to the side. Using a
low force load cell there is a high risk of its damage by permanent bending of the load
cell which is due to its constructive principle. If there is danger of the load cell
overload we recommend to use special protection equipment which we also provide
After overload the load cell still shows measurements but they are not linear anymore.
That is why we recommend to use pneumatic grips for low force tests to avoid an
accidental destruction of the load cell when tightening the clamps.
To ensure the accuracy of the load cell a calibration test should be done with different
weights. If it is necessary adjust also the calibration factor.
We can only provide the load cell function as guaranteed by the manufacture. Any
claims which are due to false fixing or overload are not accepted.
7.03 Zero Adjustment:
By pressing the [1] key before testing zero adjustment is done.
As already the clamping of specimen produces force zero adjustment should be always
done before each test.
7.04 Change of the Load Cell:
In order to change the load cell you have to do the following:
1. switch off the machine;
2. loosen the fixing screw at the crosshead;
3. mount a new load cell with the fixing screw at the crosshead;
4. put a load cell plug into the connector on the back side of the machine;
5. switch on the machine.
Each load cell has its own capacity, sensitivity and a calibration factor. That is why
each time after the change you have to enter new values.
It is done as follows:
1. press the [5] key;
2. enter the password “09122”;
3. save old parameters on a piece of paper and enter new values (from data-sheep):
- load cell capacity, e.g. 3 kN;
- load cell sensitivity, e.g. 3.1324mV/V;
- set calibration factor to “1”.
With these values you will reach approx. 1% accuracy of the load cell capacity.
19
7.05 Calibration With The Weight:
In order to increase the accuracy of the machine you have to calibrate with the weight.
It is done as follows:
- remove load from the load cell (if there is any);
- set calibration factor to “0.
The display shows the following:
(Do not be confused that the display shows the messages in German, - this program is
used seldom, that is why we did not translate into English. On the right side of the
page you see the messages translated into English).
mit Gewicht eichen
weight calibr. 1=ok
Calibrate with weight
Weight calibr. 1=ok
Confirm with the [1] key, then you see the following:
Lastzelle entlasten
weiter mit Taste
Remove load from the load
cell
When the machine does not vibrate, press any key.
Last aufbringen
weiter mit Taste
Burden the load
Now hang a known weight on the load cell, wait till it is motionless and then press any
key.
Faktor bestimmen

The machine calculates the
factor
Press any key.
Faktor bestimmen
15%
The machine calculates the
factor
15%
The machine calculates now the factor automatically, it counts from 1 till 100%.
When the procedure is completed, the machine awaits that the operator enters the force
that the load cell was loaded with.
Last: 38.460 N
Neu:
The pre-set force is 38.460 N
Enter the loaded force
20
Now you have to enter the force that the load cell was loaded with.
38.46 N
Last ok=1 again=9
The actual force is 38.46 N
Force ok =1 again=9
Because of the vibrations of the machine the last digit of the force reading is not stable.
The average value should be the same as the weight. When you are satisfied with the
calibration, press the [1] key and you will end the routine. If you press the [9] key, you
start the procedure once again.
The display shows the calculated calibration factor.

The Load Cell mustn't be deformed more than max. 0.2 mm in pulling direction!
Doing pressure tests ensure that the Load Cell does not bend out to the side!
Specially using low force Load Cells there is a high risk of damage by permanent
bending of the Load Cell which is due to the Load Cells construction principle
In case there is a danger of Load Cell overload we recommend to use special
protection equipment which we also provide. (www.grip-engineering.com)
After overload damage the Load Cell may still show measurements, but is not linear
anymore.
This is why we recommend the use of pneumatic grips for low force tests to avoid
accidentally destruction of load cells when tightening the clamps.
To ensure the accuracy of a Load Cell a calibration test should be done with multiple
different weights. If necessary adjust the calibration factor .
We only can provide the Load Cell Function as guaranteed by the manufacturer
Interface/Huppert. Any warranty claims which are due to mal -operation or overload
will not be accepted.
5.2)
Zero adjustment
By pressing " 0 " before testing a Zero adjustment is done.
As already the clamping of probes does produce forces a Zero adjustment
should always be done before testing.

change of load cells
Switch off power on the machine
-
loosen the screw at the cross bar
mount new load cell with the screw at the cross bar
put load cell plug into the connector at the back side of the machine
Switch on the machine again and wait to end of self test procedure
press "5"
type Password: "09122"
save old parameters on a piece of paper and type the new values
¾ set new parameter for ‘Loadcell’ e.g.: 2000 [N]
¾ set new parameter for ‘mV/V’
(load cell sensitivity) e.g.: 3.165 [ mV/N]
¾ set new parameter for ‘Cal’ (calibration factor) to "1"
set calibration factor with weight
put a calibration weight at the load cell, e.g. : 10 kg = 98.0665 N (**
the display should show a similar value
E.g. the display shows 95.6 N the calibration factor must be
increased:
from 1 to 1.03745 (use calculator)
check the changes with the weight again!
** (this is dependent to your location and valid for 45° northern /
e.g. at the
North pole it would be 98.32 N / at the Equator 97.80 N )
Mounting procedure of Load Cell
Caution!
Small type of load cells can easily be deformed especially by torsion
forces.
Never put torsion forces on the Load cell while tightening or loosen
probes and clamps

Mistakes:
Movement of Z10-X700 is only 500 mm
This is only limit of software (not limit of mechanic) you can't set end position more as 500mm.
Z10 use universal software from Z3-Z5.
In configuration menu (protected by password) exist parameter: "machine type" with value=5,
change this value to "6" and limit of max. end position will be now 1000mm.
Hints
you can activate a c compensation in settings
you make a measurement of a very stiff part in your grips
then you divide dF/dx and write this value to C compensation and activate
then you will only see movement of the sample not loadcell machine or grips
Autocalibration Limits of loadcell
24.4.08
In our software exist limits:
1<mV<6
( you can just use 1.001 mV/V value)
0,5<Cal<1,5
Any new load cell used with our machines must be calibrated (adapted to our electronic).
the best (most easy) way is to use auto calibration (embedded in software).
You will need some precision "check weight" elements (100g - 300g)
and some scale pan (dish) or something different to fix "check weight" on the load cell adapter.

install new load cell
in configuration menu (pass. 09122) set nominal load = 5 N
set mV/V = 1.001
set Cal = 0 (zero) -auto calibration will be activated
for question "mit Gewicht eichen?..." press key "1"
from now you have only 40 sec. for each answer (if time is over, you will need again repeat procedure from p.4)
now leave on load cell only scale pan (dish) with pin (this is "tara", we need measure only "check weight element") and
press "Return" key
now auto calibration will set "tara"
for message: "Last aubringen", install "check weight element" and press "Return" key
now auto calibration will calculate average weight
for message: "Last: 38.460" set weight in [N] of your "check weight element" (i.e. if you use 200g - set 1,961 N
(0,2*9,80665=1,96133 N))
now you get new calculated force (i.e. if you set 1,961N you will get about 1,96N)
if calculation was wrong and you need to repeat auto calibration press now key "9"
if calculation was OK, press key "1" to finish auto calibration set new calibration factor
now you will see new factor (i.e. 1,231)
this is end of auto calibration, you can go out of configuration menu.

" max. Last / Motor gestoppt" <- such message is generated in two cases:
1. load cell is demaged (overloaded - bended) and show very big (positive or negative) load over
safety limit (~2900N)
2. A/D converter on main board don't work correctly (no valid conversions).
First case you can check:
•
•
when you connect anny different load cell - you can see normal load readings on the LCD
when you remove any load cells plug from the machine - load display is "running up" or "down"
until limit (open loop).
You can also send us old load cell to check or check it self on next machine (by next customer with our
ZPM).
New load cells we have on stock.
